DESCRIPTION AND OPERATION
IGNITION SYSTEM
DESCRIPTION
The system's three main components are the coil
pack, crankshaft position sensor, and camshaft posi-
tion sensor.
OPERATION
Basic ignition timing is not adjustable.The
Powertrain Control Module (PCM) determines spark
advance. The 2.0L engines use a fixed ignition timing
system. The distributorless electronic ignition system
is referred to as the Direct Ignition System (DIS).
SPARK PLUGS
The 2.0L engines uses resistor spark plugs. For
spark plug identification and specifications, Refer to
the Specifications section at the end of this group.
Remove the spark plugs and examine them for
burned electrodes and fouled, cracked or broken por-
celain insulators. Keep plugs arranged in the order
in which they were removed from the engine. An iso-
lated plug displaying an abnormal condition indicates
that a problem exists in the corresponding cylinder.
Spark plugs that have low mileage may be cleaned
and reused if not otherwise defective. Refer to the
Spark Plug Condition section of this group. Aftercleaning, file the center electrode flat with a small
point file or jewelers file. Adjust the gap between the
electrodes (Fig. 1) to the dimensions specified in the
chart at the end of this section by bending the
ground electrode (just above the attachment weld)
with the appropriate tool.
Never apply any force between the electrode or
damage to the center electrode assembly will result.
Always tighten spark plugs to the specified torque.
Over tightening can cause distortion and damage.
Tighten spark plugs to 28 N´m (20 ft. lbs.) torque.
SPARK PLUG CABLES
Spark plug cables are sometimes referred to as sec-
ondary ignition wires. The wires transfer electrical
current from the coil pack to individual spark plugs
at each cylinder. The resistor type, nonmetallic spark
plug cables provide suppression of radio frequency
emissions from the ignition system.
Check the spark plug cable connections for good
contact at the coil and spark plugs. Terminals should
be fully seated. The nipples and spark plug covers
should be in good condition. Nipples should fit tightly
on the coil. Spark plug boot should completely cover
the spark plug hole in the cylinder head cover. Install
the boot until the terminal snaps over the spark
plug. A snap must be felt to ensure the spark plug
cable terminal engaged the spark plug.

IGNITION INTERLOCK
OPERATION
All vehicles equipped with automatic transaxles
have an interlock system. The system prevents shift-
ing the vehicle out of Park unless the ignition lock
cylinder is in the Off, Run or Start position. In addi-
tion, the operator cannot rotate the key to the lock
position unless the shifter is in the park position. On
vehicles equipped with floor shift refer to the - Tran-
saxle for Automatic Transmission Shifter/Ignition
Interlock.
REMOVAL AND INSTALLATION
SPARK PLUG SERVICE
Failure to route the cables properly could cause the
radio to reproduce ignition noise, cross ignition of the
spark plugs or short circuit the cables to ground.
REMOVAL
REMOVE CABLES FROM COIL FIRST.
Always remove the spark plug cable by grasping
the top of the spark plug insulator, turning the boot
1/2 turn and pulling straight up in a steady motion.
(1) Remove the spark plug using a quality socket
with a rubber or foam insert.
(2) Inspect the spark plug condition.
INSTALLATION
(1) To avoid cross threading, start the spark plug
into the cylinder head by hand.
(2) Tighten spark plugs to 28 N´m (20 ft. lbs.)
torque.
(3) Install spark plug insulators over spark plugs.
Ensure the top of the spark plug insulator covers the
upper end of the spark plug tube.
Reconnect to coil.
SPARK PLUG CABLE SERVICE
Failure to route the cables properly could cause the
radio to reproduce ignition noise, cross ignition of the
spark plugs or short circuit the cables to ground.
REMOVAL
Remove spark plug cable from coil first.
Always remove the spark plug cable by grasping
the top of the spark plug insulator, turning the boot
1/2 turn and pulling straight up in a steady motion.
INSTALLATION
Install spark plug insulators over spark plugs.
Ensure the top of the spark plug insulator covers the
upper end of the spark plug tube. The connect theother end to coil pack. Be sure that dual plastic clip
holds the cables off of the valve cover.
IGNITION COIL
The electronic ignition coil pack attaches directly
to the valve cover (Fig. 11).
REMOVAL
(1) Disconnect electrical connector from coil pack
(Fig. 10).
(2) Remove coil pack mounting bolts.
(3) Remove coil pack.
INSTALLATION
(1) Install coil pack on valve cover.

The coil pack towers are numbered with the cylinder
identification. Be sure the ignition cables snap onto
the towers.
AUTOMATIC SHUTDOWN RELAY
The relay is located in the Power Distribution Cen-
ter (PDC) (Fig. 12). The PDC is located next to the
battery in the engine compartment. For the location
of the relay within the PDC, refer to the PDC cover
for location. Check electrical terminals for corrosion
and repair as necessary.
CAMSHAFT POSITION SENSOR
The camshaft position sensor is mounted to the
rear of the cylinder head (Fig. 13).

DIAGNOSIS AND TESTING
HEADLAMP LEVELING SWITCH
(1) Remove the headlamp leveling switch from the
instrument panel and disconnect the wire harness
connector from the switch. Refer to Wiring Diagrams
for the proper wire circuits and the wire connector
connections.
(2) If the L. E. D. is not illuminated, using a volt-
meter, connect B+ lead to Pin 4 of the Wire harness
connector. Connect the negative lead to Pin 3. Turn
ON the headlamp switch to the low beam position
and ensure the instrument panel dimmer switch is
on day light driving position. If voltage is present,
replace switch. If no voltage, connect the ground lead
to a good ground, if voltage, repair Pin 3 ground cir-
cuit as necessary, and if no voltage, refer to Wiring
Diagrams and test circuit back to headlamp switch.
(3) Using a voltmeter, connect B+ lead to Pin 2 of
the Wire harness connector. Connect the negative
lead to Pin 3. Turn ON the headlamp switch to the
low beam position. If battery voltage, go to Step 5. If
not OK, go to Step 4.
(4) Connect the ground lead to a good ground, if no
voltage, refer to Wiring Diagrams and test circuit
back to headlamp switch. If battery voltage, repair
Pin 3 ground circuit as necessary.
(5) Turn headlamps OFF. Connect the wire har-
ness connector to the headlamp leveling switch. Turn
ON the headlamp switch to the low beam position.
Check voltage at Pin 5, while rotating the headlamp
leveling switch knob through the four positions. Thevoltage reading should change as the switch is
rotated to each position. If the voltage does not vary
replace switch. If OK, test the headlamp leveling
motors and/or circuit to the motors.
INSTRUMENT PANEL AND COMPONENTS
CAUTION: Disconnect the battery negative cable
before servicing the instrument panel or compo-
nents. When power is required for test purposes,
connect battery cable for test only. Disconnect the
battery negative cable after test and before continu-
ing service procedures.
